Answer:
$40
Step-by-step explanation:
If it was 20% off, you are paying 80% of the original price.
So .80 * Original price = $32
32/.8 = 40
Answer:
8
Step-by-step explanation:
Count each side and you get 8 sides.
Mary = 3x
Seth = X
If we know that Mary is three times older than Seth, we can set this up into an equation.
3x + x = 76
Now, we can simplify on the left side by adding the Xs together.
4x = 76
X = 19
Therefore, Seth is 19 years old and Mary is 57 years old.
